Now satellites are helping to forecast(预报) the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere (大气), because this is where the weather forms (形成). They send these pictures to the weather stations. So meteorologists(气象学家) can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
